StecaGrid 10000 3ph, StecaGrid 8000 3ph similar

StecaGrid 8000 3ph and StecaGrid 10000 3ph Always symmetricalThe advantage of three-phase feeding is that the produced solar capacity is always symmetrically distributed on all three power con-ductors to the public power grid. This is the case across the whole output range offered by these inverters. When designing a sys-tem, the laborious avoidance of an asymmetry of more than 4.6 kW through the appropriate selection of separate inverters is thus dispensed with. Symmetrical feeding is greatly in the interests of energy supply companies. Lengthy discussions with such companies are therefore a thing of the past.

Long service liveWhile the voltage passes through zero on the grid-feeding phase, single-phase inverters must temporarily accommodate all energy supplied by the solar modules within the device. This is usually reali-sed by electrolytic capacitors. These components influence the ser-vice life of an electronic device, due to the possibility of drying out.With three-phase inverters, energy is fed into the grid on at least two phases at all times. Thus, the necessity of intermediate storage of energy in the device is greatly reduced, which is of benefit to the system operator with regard to a longer service life.

Flexible connectionDue to the wide input voltage range of 350 V to 845 V, and a maxi-mum input current of 27 A / 32 A, all commonly available crystalline solar modules can be connected to the inverters in various configu-rations. Beyond this, the system is also approved for use with CdTe and CIS / CIGS thin-film modules. Five plug/socket pairs are available for flexible, mechanical DC connection.

Easy handlingDespite their high output, the inverters are wall-mounted devices. Thanks to the high degree of protection, those inverters can be in-stalled indoors or outdoors.Due to the integrated DC circuit breaker, installation work is made easier, and the installation time is reduced. It is not necessary to open the inverter during installation.

Flexible system designThe combination of the StecaGrid 8000 3ph and the Steca Grid 10 000 3ph allows optimum design for almost any power class. A diverse range of combinations are possible but they all share the same goal: the effective use of solar irradiation.
